BlackBerry 7

Although the last build, OS is still fresh for a lot of folks and working quite fine, a new OS -- v7.0.0.540 has now popped up for you all to take a run at. It's not official in any way but given the rate RIM seems to be pushing out official OS' these days it wouldn't be that much of a stretch to see it go official soon. Either way, if you're all in for testing out an OS for RIM then by all means have at it. Keep in mind, back up your data in case something funky happens.
